How Do You Find a Great Deck or Fence Contractor?
Hire a contractor who pulls permits and specifies hot-dipped galvanized or stainless structural hardware in writing, then ask for references from decks or fences built 2 to 3 years ago with no premature warping, railing loosening, or structural concerns. A well-built structure enhances a property for decades while a poor one fails inspection or deteriorates early, and because most of what determines longevity is structural and invisible once the surface goes on, the screening has to happen before anyone starts building. Require a written material specification naming brand and product for each component.
They Pull Permits and Build to Code
A quality contractor pulls the permit as part of their standard process and manages the inspection sequence. They know what the local inspector looks for and build to meet or exceed it. The permit process gets the structure reviewed for structural adequacy and code compliance, and it documents the construction for resale.
A contractor who suggests skipping the permit, usually framed as saving you money and hassle, is handing you a liability that follows the house. An unpermitted deck has no confirmed structural inspection, becomes a problem at sale, and may have to be removed. The best contractors handle permits without being asked and consider it normal professional practice.
They Specify Materials and Hardware in Writing
Fasteners and Structural Hardware
Deck longevity depends heavily on the fasteners and hardware. Stainless steel or hot-dipped galvanized screws and joist hangers are the correct choice for all structural connections; electroplated hardware can corrode and fail in exterior exposure. Hidden deck fasteners, which eliminate visible screws from the deck surface, are another quality indicator. Ask directly what fastener and hardware specification the contractor uses for structural connections. An answer that names hot-dipped galvanized or stainless steel indicates quality practice; vagueness indicates the opposite. (For more on this, see Hidden Costs of Deck and Fence Installation.)
The Written Material Specification
The quote should specify the decking product by brand and line for composite or by species and treatment for wood, the fastener specification, the post base type and product, whether surface mount or in-ground, the joist hanger specification, the post size, and the railing product and style. A quote that just says “composite decking and railing” cannot be meaningfully compared to a competing quote. A good contractor can also explain why they chose those specifications and what the alternatives would cost. Vagueness about material grade usually means either uncertainty or intentional flexibility to install something lower than what you thought you were buying.
Licensing, Insurance, and Who Should Build the Deck
A licensed contractor, where your state requires one, has met minimum competency and accountability standards. General liability insurance protects you from property damage claims during construction, and workers’ compensation covers employees injured on your property. Ask for the license number, current insurance certificates, and how long they have operated locally. Established contractors with a local presence have a reputation at stake and are more accountable than transient operators.
For any deck over $5,000, a licensed contractor with specific deck experience is strongly preferred over a general handyman. Deck structural connections, including joist hangers, beam-to-post connections, and footing specifications, require knowledge of building code requirements. A handyman without deck experience may build something that passes a visual inspection but fails under the lateral loads a deck sees in wind and during gatherings, and typically does not carry liability insurance for structural failures. (For more on this, see Deck Building Mistakes to Avoid.)
Use References the Right Way
Day-one photos of any deck look good. Construction quality shows up 2 to 3 years later, in whether boards have cupped or warped, whether the railing is still tight, whether post connections are secure, and whether premature wood decay has appeared at the connections. Ask for references from decks and fences the contractor built two or three seasons ago, not last month.
Asking a reference whether they were satisfied produces uniformly positive answers, since unhappy customers rarely agree to be listed. Ask better questions instead: How does the deck or fence look now compared to when it was installed? Did any issues emerge in the first year, and how did the contractor respond? Did the final cost match the quote? Would you use them again on a larger project?
Seeing the work in person beats a phone call whenever it is feasible. Cupped boards, rusting fasteners, a wobbling railing, fence posts that have started to lean within a year or two, or boards already checking and splitting all tell you something about installation practice that no conversation fully captures. A deck that still looks excellent three or four years on, with a solid railing and decking that has held its appearance, is the strongest evidence of quality workmanship you can get. (For more on this, see What Affects Deck and Fence Installation Cost?.)
Bids, Contracts, and Warranty
Get three bids as a minimum and compare them on identical specification: the same decking product, the same railing type, the same footing specification, and the same treatment of permit and inspection fees. A bid significantly below the others warrants scrutiny, because it usually reflects a lower material grade, shallower footings, lower-grade fasteners, or the exclusion of items the other bids include. Normalize the scope first; the lowest compliant bid on equivalent scope is worth choosing, and the lowest bid on a different scope is not a comparison at all.
The written contract should cover the scope, stating explicitly what is included and excluded, the material specifications, the timeline with a start date and what could extend it, the payment schedule, and warranty terms for both labor and materials. A reasonable payment schedule ties payments to milestones rather than requiring the full amount upfront.
Understand that the two warranties are separate. The decking manufacturer’s material warranty runs 15 to 50 years against fade and stain on composite, with no equivalent applicable to wood, and it requires installation per the manufacturer’s guidelines, so a deviation can void it. The contractor’s installation labor warranty runs 1 to 3 years against structural defects, railing loosening, and fastener failures. Confirm both before signing.

Frequently Asked Questions
Choose one who pulls permits and manages the inspection sequence, specifies hot-dipped galvanized or stainless steel structural hardware, provides a written material specification naming brand and product for each component, and can give you references from decks built 2 to 3 years ago with no premature warping, railing loosening, or structural concerns.
Because the permit process gets the structure reviewed for structural adequacy and code compliance and documents it for resale. A contractor who skips permits is asking you to carry the risk of unreviewed construction, which can require remediation or even removal when the home is sold.
Ask what fastener and hardware specification they use for structural connections, whether they pull the permit and who manages the inspection, what decking product they are quoting and what its warranty covers, and whether you can see a deck they built 2 to 3 years ago and speak with that homeowner.
Three is the standard minimum, compared on identical specification: the same decking product, the same railing type, the same footing specification, and the same treatment of permit and inspection fees. A bid significantly below the others typically reflects a lower material spec, shallower footings, lower-grade fasteners, or excluded items.
For any deck over $5,000, a licensed contractor with specific deck experience is strongly preferred. Structural connections such as joist hangers, beam-to-post connections, and footing specifications require code knowledge, and a deck built without it may pass visual inspection but fail under lateral loads. A licensed contractor also carries liability insurance for structural failures; a handyman typically does not.
Two separate warranties. The manufacturer's material warranty runs 15 to 50 years against fade and stain on composite decking, with no equivalent for wood, and requires installation per the manufacturer's guidelines. The contractor's labor warranty runs 1 to 3 years against structural defects, railing loosening, and fastener failures.
Skip asking whether they were satisfied, since listed references are uniformly positive. Ask how the deck or fence looks now compared to installation day, whether issues emerged in the first year and how the contractor responded, whether the final cost matched the quote, and whether they would use the contractor again on a larger project.
The scope stating exactly what is included and excluded, material specifications with product, grade, and dimensions, the timeline with a start date and what could extend it, a payment schedule that is not 100 percent upfront, and warranty terms for both labor and materials. Vagueness on any of these creates dispute potential later.
